Using Machine Learning Techniques for Polar Vortex Predictions
A new model accurately reproduces aspects of polar vortex behavior, extracting indicators of imminent vortex collapse and accompanying frigid weather in North America and Europe.
The Ambiguous Costs of Climate Change
To put a price tag on climate change, some approaches focus on whether it made an event more likely, whereas others focus on whether it made an event more severe and damaging. A new study examines the validity of both approaches.
Clouds over the Highest Mountains Dance a Little Differently
Clouds over the Tibetan Plateau and the Andes are growing colder and higher than other clouds in response to climate change. That could affect local hydrology and radiation.
Melting Permafrost Impacts Arctic Rivers in Vulnerable Regions
Changes in river chemistry in the northwestern North American Arctic reflect increased acid rock drainage associated with permafrost thaw, an unexpected consequence of Arctic warming.
A Hydrological Paradox on the Silk Road
How did trade prosper in Central Asia during a period of droughts and little rain?
2026 State of the Climate Report Shows a Planet Reaching Its Limits
The seventh edition of an annual report analyzing Earth’s “planetary vital signs” indicates that Earth systems are rapidly destabilizing, some at an accelerating rate.
The report, published today in BioScience, analyzed 16 of these signs, including greenhouse gas emissions levels, ocean heat content and acidity, the mass of major ice sheets, the number of hot…
Patchier Permafrost Is Linked to More Intense Hillslope Erosion
Arctic landscapes with spots of disconnected permafrost erode faster than those with continuous permafrost, a new study finds.
Reading Rainfall in a Snail’s Shell
The chemical record of a snail shell is allowing scientists to reconstruct a record of past storms from the recent—and maybe distant—past.
Reliable AI Sea Ice Forecasts Depend on Sustained Observations
Sea ice is a fundamental regulator of Earth’s climate and an increasingly urgent forecast target itself. Can we trust the AI systems now being built to predict it?
Limits of Satellite Detection of Extreme Carbon Cycle Events
Satellite carbon dioxide observations detect more carbon-cycle extremes than ground stations but still miss many events and underestimate their magnitude.
